AQUAFIN-RAPIDFLEX-213
Non-foaming Polyurethane
Description:
AQUAFIN-RAPIDFLEX-213 is a new generation of highly-reactive two-component injection resins used for sealing joints and cracks in concrete and stone. It has been especially developed for injecting against flowing water. By combining a special polymer dispersion with hydrophilic polyurethane prepolymers a material is developed which hardens to a rubbery, elastomeric mass with high tensile and compressive strength and which does not need to be re-injected.
RAPIDFLEX-213 physically absorbs water from the surroundings, which guarantees that the hardened material has a homogenous structure. It prevents the formation of voids resulting from trapped water within its structure and therefore, the material does not become weakened over time.
RAPIDFLEX-213 adheres tenaciously to both damp and dry joint flanks and other surfaces such as concrete, stone, etc. Adhesion is further improved by the formation of a microfoamlike structure (max. 3 % expansion in volume). The pressure resulting from the expansion creates a waterproof barrier which resists infiltration of water into typical foaming urethane grout products.

Typical Applications:
- For injection of cracks with high waterflow in concrete, stone, etc.
- To repair leaking expansion joints
Benefits:
- Added flexibility where movement might occur
- Can be injected against water pressure
- High compressive and flexural strenght
- Bonds to wet and dry surfaces, compatible with water
- Re-injection not necessary
- Extremely quick reaction time, without effecting material flow
CSI Divisions:
- Injection Grouting (03 64 00)
